ALCS- Enviromental issues on athletes
Everything You Think is Safe
An athlete increases their chance of becoming effected by the harmful substances of their environment because of the frequency of exposure to that threat and the intensity of effort exerted in that environment. Tobacco smoke, indoor air pollution, ice arena air pollution, problems in pools, and a few other similar things are the main problems and places that athletes take part in that can hurt them. These environmental issues hurt the common athlete by as little as eye and throat irritation which can affect their capabilities.

Artificial Turf
In a study of artifical turf, scientists found harmful chemicals in virtually every sample tested, including PAHs, chromium and lead.
Arsenic and cadmium were detected in most samples.
Tests with synthetic saliva, gastric juice and intestinal fluids showed that some of the contaminants were biologically available.
Potential risks to children and adults using these areas should be evaluated since nearly 1,000 fields of artificial turf are installed every year in the U.S.

The Temperature Even Affects Them
The ability to perform vigorous exercise for long periods is limited by hyperthermia (over heating) and loss of water and salt in sweating. Athletes should know the hazards of vigorous exercise in hot, humid conditions and should be able to recognise the early warning symptoms that precede heat injury.
The circulatory system functions first to deliver nutrients to the working tissues and remove the waste products; and secondly to regulate the transfer of heat from active muscles to the body surface.

It is because of this added demand on blood flow that body temperature regulation, and circulatory capacity, are significantly influenced by the environmental temperature and humidity.
When performing in warm, humid conditions the circulation cannot both supply nutrients to muscle and regulate body temperature to the complete satisfaction of the body. As a result, the athlete's performance is impaired, and overheating becomes a serious problem.
